{{lowercase|de Havilland Canada}}
The '''de Havilland Canada''' company was an aircraft manufacturer with facilities based in what is now the [[Downsview]] area of [[Toronto]], [[Ontario]], Canada. The original home of de Havilland Canada is now the home of the [[Toronto Aerospace Museum]] located in what is now [[Parc Downsview Park]].
The aircraft company was created in 1928 by British [[de Havilland|de Havilland Aircraft Company]] to build Moth aircraft for the training of Canadian airmen, and subsequently after the Second World War, designed and produced indigenous designs. After a number of company changes, [[Bombardier]] sold the rights to the out-of-production aircraft (DHC-1 through DHC-7) to [[Viking Air]] Ltd. of [[Sidney, British Columbia]], in May 2005.

==Pre-Second World War==
Flown for the first time on [[26 October]] [[1931]], the [[de Havilland Tiger Moth|DH.82 Tiger Moth]] was derived from the [[de Havilland Moth|DH.60 Moth]]. The DH 82 was powered by a 120 hp Gipsy II engine, but the 1939 DH.82a received the 145 hp Gipsy Major. More than 1,000 Tiger Moths were delivered before the [[Second World War]], and subsequently 4,005 were built in the UK and shipped all over the world. 1,747 were built in Canada (the majority being the DH.82c model with enclosed cockpits, brakes, tail wheels, etc.). The follow-up [[De Havilland Fox Moth|DH.83 Fox Moth]] was designed in England in 1932 as a light, economic transport and was built using as many Tiger Moth components as possible.
==Second World War==
The [[de Havilland Tiger Moth]] was a basic trainer of the [[British Commonwealth Air Training Plan]] (BCATP) during the Second World War, whereby air crews from all over the [[Commonwealth of Nations|British Commonwealth]] trained in Canada. DHC was a [[Canadian]] unit of [[United Kingdom|British]] [[de Havilland]] and during [[World War II]] was made into a [[crown corporation]] of the [[Canada|Canadian]] government.
Production of the de Havilland DH.98 Mosquito nicknamed the "Mossie," was the company's greatest contribution to the war effort. The [[de Havilland Mosquito]] was one of the most remarkable combat aircraft of the Second World War; the most striking feature of the aircraft was its construction. To reduce wartime metal use, the airframe was constructed almost entirely out of plywood. The design intent of the Mosquito was speed instead of defensive armament, and from the moment it first flew until the development of the [[Messerschmitt Me 262|Me-262]], it was the fastest plane in the war, at 425 mph at 30,000 feet. Its manoeuverability, even on just one engine, was spectacular. The original design was intended as a light bomber, but soon proved itself in high-level photography and every phase of intruder operations.
==Post-Second World War==
After the war, de Havilland Canada began to build its own designs uniquely suited to the harsh Canadian operating environment. The company also continued production of several British de Havilland aircraft and later produced a license-built version of the American-designed [[S-2 Tracker|Grumman S2F Tracker]]. The [[Avro Canada]] aircraft production facility was transferred to de Havilland Canada by the companies' parent [[Hawker Siddeley]] in 1962.
===DHC-1 Chipmunk===
[[Image:RCAF Chipmunk 18041.jpg|thumb|right|A former [[Royal Canadian Air Force]] ''(RCAF)'' Chipmunk]]
The first true postwar aviation project was the [[de Havilland Canada DHC-1 Chipmunk|de Havilland DHC-1 Chipmunk]], designed as a primary trainer, a replacement for the venerable de Havilland Tiger Moth. The Chipmunk was an all-metal, low wing, tandem two-place, single-engine airplane with a conventional tail wheel landing gear. It had fabric-covered control surfaces and a clear plastic canopy covering the pilot and passenger/student positions. The production versions of the airplane were powered by a 145 hp in-line de Havilland Gipsy Major "8" engine.
The Chipmunk prototype first flew on [[22 May]] [[1946]] in Toronto and had a total production run of 158 Chipmunks for RCAF use while de Havilland (UK) produced 740 airplanes for training at various RAF and University Air Squadrons during the late 1940s and into the 1950s. The DHC-1 Chipmunk was still being used as a training aircraft by the UK's Army Air Corps up until 1995.
===DHC-2 Beaver===
Returning to designing purpose-built aircraft for Canada's north, [[de Havilland Canada DHC-2 Beaver]] was developed in 1947. After a survey of Canada's bush pilots, including the great [[Punch Dickins]], the need for a rugged, highly versatile aerial truck which could take off and land almost anywhere, carry a large half-ton load and be very reliable, formed the basis of a new specification. The first of the STOL family that de Havilland would produce, the Beaver would carve a niche into the bush plane market.
In the civilian sector, the Beaver soon excelled on wheels, skis and floats, so it was almost inevitable, that, in 1951, the Beaver would be selected by the US Air Force and Army as a new liaison aircraft. In the nine years that followed, 968 L-20As were delivered to the armed forces, most going to the Army. They served in both the Korean and Vietnam wars, hauling freight and personnel around the battlefields, mapping enemy troop positions, leading search/rescue missions, and relaying radio traffic, among other missions. In 1962, the L-20 was re-designated the U-6A, and many remaining examples remained in service well into the 1970s. Beavers were also purchased and used by the military services of numerous other nations, including Britain, Chile and Colombia.
With almost 1700 built in a production run lasting two decades, civilian-owned Beavers continue plying their trade in over 50 countries all around the world. A turbine-conversion, the Turbo-Beaver first flew in December 1963. This version featured a Pratt & Whitney PT6A6 turboprop, which offered lower empty and higher takeoff weights, and even better STOL performance. The Turbo Beaver's cabin was also longer, allowing maximum accommodation for 11, including the pilot. Externally, the Turbo Beaver had a much longer and reprofiled nose, and squared off vertical tail. DHC also offered conversion kits enabling piston powered Beavers to be upgraded to Turbo standard. Other conversions have been performed by a number of companies including Kenmore Aviation and Viking Air.
===DHC-3 Otter===
[[Image:C-FUKN-Northway-Aviation-DHC-3-Otter-2.jpg|thumb|right|C-FUKN piston Otter on floats in [[Manitoba]], [[Canada]]]]
Another in de Havilland Canada's successful line of rugged and useful STOL utility transports, the [[de Havilland Canada DHC-3 Otter|Otter]] was conceived to be capable of performing the same roles as the earlier and highly successful Beaver, but was bigger, the veritable "one-ton truck."
Using the same overall configuration of the earlier and highly successful DHC2 Beaver, the Otter is much larger overall. The Otter began life as the King Beaver, but compared to the Beaver is longer, has greater span wings and is much heavier. Seating in the main cabin is for 10 or 11, whereas the Beaver could seat six. Power is supplied by a 450 kW (600 hp) Pratt & Whitney R1340 Wasp radial. Like the Beaver, the Otter can be fitted with skis and floats. The amphibious floatplane Otter features a unique four unit retractable undercarriage, with the wheels retracting into the floats.
Design work at de Havilland Canada began on the DHC3 Otter in January 1951, the company's design efforts culminating in the type's first flight on [[12 December]] [[1951]]. Canadian certification was awarded in November 1952.
After de Havilland Canada demonstrated the Otter to the US Army, subsequently that service went on to become the largest DHC3 operator (as the U1). Other military users included Australia, Canada and India.
Small numbers of Otters were converted to turbine power by Cox Air Services of Alberta, Canada. Changes included a Pratt & Whitney Canada PT6A turboprop, a lower empty weight of 1692 kg (3703 lb) and a higher maximum speed of 267 km/h (144 kt). It was called the Cox Turbo Single Otter. A number of other after market PT6 conversions have also been offered.
The Otter found a significant niche as a bush aircraft and today it remains highly sought after.
===DHC-4 Caribou===
de Havilland Canada's fourth design was a big step up in size compared with its earlier products, and was the first powered by two engines, but the [[de Havilland Canada DHC-4 Caribou|Caribou]] was similar in that it is a rugged STOL utility. The Caribou was primarily a military tactical transport that in commercial service found itself a small niche in cargo hauling.
de Havilland Canada designed the DHC-4 in response to a US Army requirement for a tactical airlifter to supply the battlefront with troops and supplies and evacuate casualties on the return journey. With assistance from Canada's Department of Defence Production, DHC built a prototype demonstrator that flew for the first time on [[30 July]] [[1958]].
Impressed with the DHC4's STOL capabilities and potential, the US Army ordered five for evaluation as YAC-1s and went on to become the largest Caribou operator, taking delivery of 159. The AC-1 designation was changed in 1962 to CV-2, and then C-7 when the US Army's CV-2s were transferred to the US Air Force in 1967. US and Australian Caribou saw extensive service during the Vietnam conflict. In addition some US Caribou were captured by North Vietnamese forces and remained in service with that country through to the late 1970s. Other notable military operators included Canada, Malaysia, India and Spain.
The majority of Caribou production was for military operators, but the type's ruggedness and excellent STOL capabilities also appealed to a select group of commercial users. US certification was awarded on [[23 December]] [[1960]]. AnsettMAL, which operated a single example in the New Guinea highlands, and AMOCO Ecuador were early customers, as was Air America (a CIA front in South East Asia during the Vietnam War era for covert operations). Other Caribou entered commercial service after being retired from their military users.
Today only a handful are in civil use.
===DHC-5 Buffalo===
[[Image:DehavillandCC-115Buffalo12.JPG|thumb|right|[[Canadian Forces Air Command]] CC-115 Buffalo of [[No. 442 Squadron RCAF|442 Squadron]]]]
Known originally as the Caribou II, the [[de Havilland Canada DHC-5 Buffalo]] tactical transport was basically an enlarged DHC-4 with turboprop engines employing a high-set wing, upswept aft fuselage with loading ramp and T-tail. The DHC-5 had been developed to meet the requirements of the US Army for a transport that would be able to carry loads such as the Pershing missile, a 105-mm howitzer or 3/4-ton truck. Development costs were shared by the US Army, Canadian government and de Havilland Canada; the first of these transports made its maiden flight on [[9 April]] [[1964]].
Hopes for large orders were dashed when the US Army abandoned fixed-wing aircraft. 122 were built in two production runs, including a handful of Buffalo aircraft for the US Army and four C-8 transports for the USAF. When no further orders resulted from the US Army evaluation of the DHC-5 (designated originally YAC-2 by the US Army, and later C-8A), the Canadian Armed Forces acquired 15 of the DHC-5A (designated CC-115): six were converted subsequently for deployment in a maritime patrol role.
Following delivery of 24 to the Brazilian Air Force and 16 to the Peruvian Air Force, the production line was closed down. In 1974, the company realised there was a continuing demand for the Buffalo and production of an improved Buffalo (DHC-5D) was initiated. This version had more powerful engines which permitted operation at higher gross weights, and offered improved all-round performance. In the early 1980s, de Havilland Canada attempted to modify the Buffalo for civilian use. The aircraft was to be branded as the "Transporter." After loss of the demonstration aircraft (SN 103 C-GCTC) at the 1984 Farnborough Airshow, the project was abandoned. Production of the Buffalo ended in 1982, but the last of 122 aircraft built was not delivered until April 1985.
===DHC-6 Twin Otter===
[[Image:Twin Otter 4 1997-08-02.jpg|thumb|right|DHC-6 Twin Otter on [[Beechey Island]], [[Nunavut]], [[Canada]]]]
Still Canada's most successful commercial aircraft program with more than 800 built, the [[de Havilland Canada DHC-6 Twin Otter]] remains popular for its rugged construction and useful STOL performance.
Development of the Twin Otter dates back to January 1964, when de Havilland Canada started design work on a new STOL twin turboprop commuter airliner (seating between 13 and 18) and utility transport to replace the earlier single-engined DHC-3 Otter. The new aircraft was designated the DHC-6 and prototype construction began in November that year, resulting in the type's first flight on [[20 May]] [[1965]]. After receiving certification in mid-1966, the first Twin Otter entered service with long-time de Havilland Canada supporter, the Ontario Department of Lands and Forests.
The first production aircraft were Series 100s. Design features included double slotted trailing edge flaps and ailerons that can act in unison to boost STOL performance. Compared with the later Series 200s and 300s, the 100s are distinguishable by their shorter, blunter noses.
The main addition to the Series 200, which was introduced in April 1968, was the extended nose, which, together with a reconfigured storage compartment in the rear cabin, greatly increased baggage stowage area.
The Series 300 was introduced from the 231st production aircraft in 1969. It too featured the lengthened nose, but also introduced more powerful engines, thus allowing a 450kg (1000lb) increase in takeoff weight and a 20 seat interior. Production ceased in late 1988. In addition, six 300S enhanced STOL performance DHC-6-300s were built in the mid 1970s.
All models have been fitted with skis and floats.
===de Havilland Canada Dash 7===
[[Image:IMG 0686-dash-7.jpg|thumb|right|A [[De Havilland Canada Dash 7|Dash-7]] belonging to the [[British Antarctic Survey]] at [[Stanley, Falkland Islands]]]]
The pinnacle of the de Havilland Canada STOL family was the four-engine [[de Havilland Canada Dash 7]] which remains unrivalled because of its impressive STOL performance and low noise capabilities.
The Dash 7 was designed as a STOL (short takeoff and landing) 50-seat regional airliner capable of operating from strips as short as 915 m (3000 ft) in length. The main design features to achieve such a capability were an advanced wing and four Pratt & Whitney PT6A turboprops. Double slotted trailing edge flaps run the entire span of the high mounted wing, dramatically increasing the lifting surface available for takeoff. Extra lift is also generated by the airflow over the wing from the relatively slow turning propellers. The wings also feature two pairs of spoilers each - the inboard pair also operate as lift dumpers, the outboard pair can act differentially in conjunction with the ailerons to boost roll control.
Financial backing from the Canadian Government allowed the launch of the DHC7 program in the early 1970s, resulting in the maiden flight of the first of two development aircraft on [[March 27]] [[1975]]. The first production Dash 7 flew on [[3 March]] [[1977]], the type was certificated on [[May 2]] [[1977]] and it entered service with Rocky Mountain Airways on [[3 February]] [[1978]].
The standard passenger carrying Dash 7 is the Series 100, while the type was also offered in pure freighter form as the Series 101. The only major development of the Dash 7 was the Series 150, which featured a higher max. takeoff weight and greater fuel capacity, boosting range. The Series 151 was the equivalent freighter. Production of the Dash 7 ended in 1988, following Bombardier's takeover of de Havilland Canada.
===de Havilland Canada Dash 8===
[[Image:Dehav.dash8.750pix.jpg|thumb|right|A 78-seat Q400 (Dash 8) operated by British European.]]
De Havilland Canada began development of the [[de Havilland Canada Dash 8|Dash 8]] in the late 1970s in response to what it saw as a considerable market demand for a new generation 30 to 40 seat commuter airliner. The first flight of the first of two preproduction aircraft was on [[20 June]] [[1983]], while Canadian certification was awarded on [[September 28]] [[1984]]. The first customer delivery was to norOntair of Canada on [[23 October]] [[1984]].
Like the Dash 7, the Dash 8 features a high mounted wing and T-tail, an advanced flight control system and large full length trailing edge flaps. Power is supplied by two Pratt & Whitney Canada PW120 series (originally designated PT7A) turboprops.
==Aircraft built under license==
The de Havilland Canada company produced a large number of aircraft under license, mostly versions of designs from its original parent company, British [[de Havilland|de Havilland Aircraft]].
===de Havilland Fox Moth===
Fox Moths were produced in Canada after the Second World War mainly to keep the plant in production, but also to satisfy the increasing need for new bush aircraft. All the Canadian modifications made to the Tiger Moth were also applied to the Fox Moth. De Havilland designed a special stretcher for the Fox Moth, in order that it could operate as an air ambulance. Of the 53 produced, 39 remained in Canada, most of which were operated in float/ski configuration and gave years of satisfactory service.
The Fox Moth, though efficient, was a bit of an anachronism. For example, a modern, moulded- plexiglas sliding cockpit-hood was attached to what was essentially a 1932 aircraft. Communication between the passenger cabin in the fuselage and the cockpit to the rear was through a hole in the instrument panel.
===de Havilland Mosquito===
Before the end of the Second World War, de Havilland Canada built 1,134 Mosquitos, of which 444 were on strength with the RCAF in models Bomber Mk VII through Trainer Mk 29 from [[1 June]] [[1943]] to [[28 September]] [[1951]].
===de Havilland Canada (Grumman) CS2F Tracker===
In 1954, the [[Royal Canadian Navy]] decided to replace its fleet of obsolescent [[TBF Avenger|TBM Avenger]] [[anti-submarine warfare]] (ASW) aircraft with domestically-produced license-built versions of the new [[Grumman]] [[S-2 Tracker|S2F Tracker]]. The contract for the CS2F was worth $100 million Canadian, at the time, the largest post-Second World War Canadian defense contract. Subassemblies of the aircraft would be produced by various Canadian companies and shipped to de Havilland Canada facilities, where de Havilland would build the forward fuselage and crew compartment, assemble the aircraft, oversee installation of the ASW electronics and prepare the aircraft for delivery.
The first Canadian-built Tracker flew on [[31 May]] [[1956]]. A total of 99 Trackers were produced for RCN service starting in the same year.<ref>Tate, Colonel D.H.[http://www.aviation.technomuses.ca/pdf/Grumman_CS2F-CP121_Tracker.pdf "Canada Aviation Museum Aircraft: Grumman CS2F / CP-121 Tracker"] Retrieved: [[28 April]] [[2006]].</ref> A few of these aircraft would serve with the Canadian military until the 1990s.
==The End of de Havilland Canada==
In the 1980s, the [[Canadian]] government privatized DHC and sold the aircraft company to then [[Seattle]]-based [[Boeing]]. DHC has since been acquired by [[Montreal]]-based [[Bombardier Aerospace]]. The de Havilland (Canada) company was eventually incorporated into the Bombardier group of companies and the Dash Eight remains in production with a particular emphasis being placed on its quiet operation in comparison to other aircraft of a similar size.
On [[24 February]] [[2006]], [[Viking Air]] of [[Victoria, British Columbia|Victoria]] purchased the [[type certificate]]s from [[Bombardier Aerospace]] for all the original De Havilland designs<ref>[http://aiabc.com/artman/publish/printer_47.shtml "Viking acquires de Havilland Canada type certificates."] Viking Press Release, [[24 February]] [[2006]].</ref> including:
* DHC-1 Chipmunk
* DHC-2 Beaver
* DHC-3 Otter
* DHC-4 Caribou
* DHC-5 Buffalo
* DHC-6 Twin Otter
* DHC-7 Dash 7
The ownership of the certificates gives Viking the exclusive right to manufacture new aircraft.
Despite its demise, de Havilland Canada has left a legacy of innovative and unique aerospace designs and its products are still flying in considerable numbers worldwide.<ref>[http://www.aircraft.airframe.org.uk/dehavillandcanada/ De Havilland Canada]</ref>
